I didn't have an OS9 system during the Coco's heyday (didn't even have a
floppy drive).  Many years later I finally got to learn about OS9, and it
blew me away.  It's like unix, if unix was written in asm instead of C.
Early unix was seen as an OS "by programmers, for programmers".  Doing asm
work on OS9 is similar(ish) to doing C work on unix.. it just feels right.
